Description

A kind of vacuum glass metallic silicon composite support support point

Technical field：

The utility model belongs to vacuum glass technical field, and in particular to a kind of vacuum glass metallic silicon composite support Point.

Background technology：

The basic structure of vacuum glass is that the essentially identical glass of two chip sizes is oppositely arranged, with battle array between two sheet glass Row form is equipped with supporting point, and vacuumizes seal chamber to form vacuum chamber after glass sandwich surrounding is closed, to realize it is heat-insulated, The physical property of sound insulation, is widely used in building facilities.Now most widely used supporting point structure be it is cylindrical and Circular ring shape, and the supporting point being clipped between glass subjects huge pressure, and also the position location of supporting point is easy displacement, this Also all there is certain shortcoming in outer existing structure, the transparency of cylindrical support point is poor, big with the contact area of glass, Thermal conductivity is larger, and middle section transmits heat but do not undertake pressure mainly, and vacuumizing rear upper and lower surface, there are still residual gas It can not be discharged；And circular ring shape wall cylindrical support point is further improved, and the part that middle part mainly undertakes stress is eliminated, And material reduces, thermal conductivity becomes smaller, but the residual gas of middle section can not be discharged, and influences the vacuum degree of vacuum glass.

Utility model content：

The utility model is to overcome drawbacks described above, provides that a kind of supporting point unshifts, thermal conductivity is small, remaining among supporting point The good vacuum glass metallic silicon composite support support point of effect is discharged in gas.

The technical solution adopted in the utility model is：A kind of vacuum glass metallic silicon composite support support point, including：Support Cylinder and silicon solder flux, the support tube are olive-type, and support tube includes convex outer tube wall and hollow inside convex outer tube wall Cavity, the hollow cavity are cylindrical type, sidewall notches are uniformly provided on the hollow cavity inner wall of support tube, in convex outer barrel The top of wall offers cross fluting, and fluting makes to form spaced convex fulcrum at the top of convex outer tube wall；The silicon Solder flux fills up the hollow cavity of support tube.

Preferably, the vertical sectional shape of the sidewall notches is semicircle or cylindrical or isosceles triangle.

Preferably, the height ratio of the height of the convex fulcrum and support tube is 1：6.

The utility model has the beneficial effects that：

1, in order to which the supporting point made to be arranged between surface glass and bottom glass can keep good support effect, simultaneously Also it can realize that supporting point is designed to the support tube of olive-type by preferably heat-insulated and scavenging action, the utility model, by support tube Inside be designed to hollow cavity, and the convex fulcrum being spaced apart is equipped in the open top of support tube, convex fulcrum can be with Reduce the contact area with glass, the residual gas of support tube middle section can be discharged again for interval setting, improve vacuum glass Vacuum degree；

2, by opening up groove on the hollow cavity inner wall of support tube, making can be with support after the silicon solder melts of filling The inner wall of cylinder combines even closer, ensures that support tube undertakes pressure and does not generate displacement, and silicon solder flux is relative to metal For thermal coefficient it is smaller.

Description of the drawings：

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the vertical view of Fig. 1；

Fig. 3 is the example of sidewall notches；

Fig. 4 is that the utility model is located at the location diagram in vacuum glass；

Wherein：1 support tube, 11 convex outer tube walls, 12 sidewall notches, 13 convex fulcrums, 2 silicon solder flux, 3 surface glasses, 4 bottom glass Glass, 5 weld ddge agent.

Specific implementation mode：

As depicted in figs. 1 and 2, the utility model is a kind of vacuum glass metallic silicon composite support support point, including：Support tube 1 and silicon solder flux 2, support tube 1 can select metal material or metal alloy compositions.The support tube 1 is olive-type, support tube 1 Hollow cavity including convex outer tube wall 11 and inside convex outer tube wall 11, due to convex outer tube wall 11 be in olive-type, two The diameter at end is less than the diameter of middle section, and convex outer tube wall 11 compares circular ring type outer wall, and the bearing capacity in the middle part of the shape is more By force.The hollow cavity is cylindrical type, and the silicon solder flux 2 fills up the hollow cavity of support tube 1.

As shown in figure 3, in order to make the silicon solder flux 2 of filling melt after can be combined even closer with the inner wall of support tube 1, Ensure that support tube 1 undertakes pressure and does not generate displacement, sidewall notches are uniformly provided on the hollow cavity inner wall of support tube 1 12, the vertical sectional shape of the sidewall notches 12 can select semicircle or cylindrical or isosceles triangle.

For the ease of the discharge of 1 internal gas of support tube, while reducing the thermal conductance between support tube 1 and surface glass 3, The top of convex outer tube wall 11 offers cross fluting, and fluting makes to form the convex of uniform intervals setting on convex outer tube wall 11 Type fulcrum 13, the convex fulcrum 13 raise up along the axial direction of support tube 1, and convex fulcrum 13 is that upper bottom is less than bottom Structure, the convex fulcrum 13 of the structure will also play support and make while reducing the contact area with 1 inner wall of surface glass With, otherwise too small contact area will bursting stress, such as convex fulcrum 13 and 3 inner wall of surface glass are point contact.Although convex The setting of type fulcrum 13 can play a supporting role, and the excessive gas inside support tube 1 is discharged after capable of playing heating, but Support effect, therefore the height of convex fulcrum 13 described in the utility model and support tube 1 can be influenced by being excessively high convex fulcrum 13 Height ratio be 1：6, the ratio height ratio is 1：2-1：For 5, preferable support effect is had.

The course of work：

As shown in figure 4, first, two blocks of glass of shapes and sizes pair of the vacuum glass made as needed carry out cut place Secondly bottom glass 4 is horizontally arranged, support tube 1 is prepared on bottom glass 4, then silicon solder flux 2 is filled into hollow cavity by reason, Then surface glass 3 and bottom glass 4 are subjected to lid conjunction, close and weld ddge agent 2 is uniformly coated on surface glass 3 and 4 interlayer of bottom glass after piece Surrounding on the outside of, after the heating, vacuum processing for finally carrying out high temperature furnace, silicon solder flux 2 in support tube 1 melts, the silicon weldering after fusing Support tube 1 is welded between surface glass 3 and bottom glass 4 by agent 2 makes support tube 1 fix and be unable to displacement.

The preferable specific implementation mode of the above, only the utility model, these specific implementation modes are all based on this Different realization methods under utility model general idea, and the scope of protection of the utility model is not limited thereto, it is any ripe Know those skilled in the art within the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in, all It should cover and be within the protection scope of the utility model.Therefore, the scope of protection of the utility model should be with claims Subject to protection domain.
